Description

Technical Field

[0001] This utility model relates to the field of PVC sheet production technology, specifically to a high-ductility PVC sheet production equipment with anti-aging properties. Background Technology

[0002] Anti-aging, high-ductility PVC sheets improve their anti-aging performance by adding additives such as light stabilizers, heat stabilizers, and anti-aging agents. Among them, light stabilizers can absorb or reflect ultraviolet rays, heat stabilizers inhibit high-temperature dehydrochlorination reactions, and some anti-aging agents have antioxidant effects. At the same time, plasticizers are added and the molecular structure is adjusted to improve ductility.

[0003] In the prior art, Chinese Patent Publication No. CN218201306U discloses a PVC sheet conveying device, including a base. A fixed frame is fixedly installed on one side of the top of the base. Three conveying rollers are rotatably arranged at the top inside the fixed frame, and two conveying rollers are rotatably arranged at the bottom inside the fixed frame. The five conveying rollers are evenly spaced. A first support plate and a second support plate are fixedly installed on both sides of the other side of the top of the base. A servo motor is fixedly installed on the outside of the first support plate, and a first insertion post connected to the servo motor is fixedly installed on the other side of the first support plate. By starting the servo motor, the winding drum is driven to rotate. At this time, the PVC sheet passes through the five conveying rollers in sequence and is conveyed to the surface of the winding drum for winding. By rotating the screw, the second insertion post is driven to pull out the winding drum, and then the winding drum is disassembled and replaced. This simplifies the disassembly and assembly steps of the winding drum and improves work efficiency.

[0004] Based on the above materials, dust adheres to the outer surface of PVC sheets during production. Current technology involves directly winding the PVC sheets after they are conveyed, causing the dust on the surface of the PVC sheets to be wound up as well, thus affecting the subsequent use and sale of the PVC sheets. Therefore, further improvements are needed. Utility Model Content

[0005] The purpose of this invention is to provide a production equipment for anti-aging, highly ductile PVC sheets, in order to solve the problem mentioned in the background art that dust adheres to the outer surface of PVC sheets during production. The existing technology directly winds up the PVC sheets after they are conveyed, causing the dust on the surface of the PVC sheets to be wound up as well, thus affecting the subsequent use and sale of the PVC sheets.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a production equipment for anti-aging, high-ductility PVC sheets, comprising a main body and PVC sheets. The inner wall of the main body is provided with a conveying roller, and a winding roller is fixedly installed at the end of the main body. The inner wall of the main body is provided with a cleaning mechanism for removing dust from the surface of the PVC sheets. The cleaning mechanism includes a first cleaning roller and a second cleaning roller rotatably installed on the inner wall of the main body. A first end face gear is fixedly installed at the end of the first cleaning roller, and a second end face gear is fixedly installed at the end of the second cleaning roller. A drive motor is fixedly installed on the outer wall of the main body, and a drive shaft is fixedly installed at the output end of the drive motor, with a drive gear fixedly installed at the end of the drive shaft. The end of the second cleaning roller is provided with a pressing mechanism for pressing the second cleaning roller.

[0007] Furthermore, the first cleaning roller is located between the conveying roller and the take-up roller, and the first cleaning roller and the take-up roller are on the same horizontal plane, and the outer wall of the first take-up roller is in contact with the bottom outer wall of the PVC sheet.

[0008] Furthermore, the second cleaning roller is located on top of the first cleaning roller, and the second cleaning roller is arranged parallel to the first cleaning roller, and the outer wall of the second cleaning roller is attached to the top outer wall of the PVC sheet.

[0009] Furthermore, the drive gear is a long gear, and the drive gear is meshed with both the first end face gear and the second end face gear.

[0010] Furthermore, the extrusion mechanism includes an adjustment block slidably installed inside the equipment body, and a slider is fixedly installed on the outer wall of the adjustment block. A guide rod is fixedly installed inside the equipment body, and an extrusion spring is sleeved on the outer wall of the guide rod.

[0011] Furthermore, the adjusting block is arranged in a circular shape and is rotatably connected to the end of the second cleaning roller. The adjusting block is symmetrically arranged at both ends of the second cleaning roller, and two sets of sliders are symmetrically arranged on the outer wall of the adjusting block.

[0012] Furthermore, the outer wall of the main body of the device is provided with a sliding groove corresponding to the adjusting block and the slider. Two sets of guide rods are symmetrically arranged on the inner wall of the sliding groove, and the length of the guide rod is the same as the length of the sliding groove. The guide rod is slidably connected to the slider.

[0013] Furthermore, one end of the compression spring is in contact with the outer wall of the top of the slider, and the other end of the compression spring is in contact with the inner wall of the top of the groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This anti-aging, high-ductility PVC sheet production equipment, by setting a first cleaning roller and a second cleaning roller that are attached to the surface of the PVC sheet, can simultaneously perform dust removal operations on the upper and lower surfaces of the sheet. The first cleaning roller is attached to the bottom of the sheet, and the second cleaning roller is attached to the top of the sheet, forming a double-sided cleaning structure. Compared with the traditional single-sided cleaning method, it can more thoroughly remove the dust attached to the surface of the sheet, avoiding dust residue from affecting the quality of the sheet and subsequent use.

[0016] 2. Through the cooperation of the adjusting block, slider, guide rod and extrusion spring of the extrusion mechanism, the adjusting blocks at both ends of the second cleaning roller can slide in the groove. The extrusion spring provides elastic support force. When the thickness of the PVC sheet changes, the adjusting block can automatically adapt to the thickness of the sheet. The contact pressure between the cleaning roller and the sheet surface is adjusted by the compression or extension of the spring. This ensures that the cleaning roller and the sheet are in close contact to effectively remove dust, while avoiding excessive pressure that could damage the sheet surface. This improves the compatibility and adaptability of the equipment to sheets of different specifications.

[0017] 3. The design utilizes a drive motor to simultaneously mesh with the first and second end face gears via a drive gear. Only one drive source is needed to achieve synchronous reverse rotation of the two cleaning rollers. This structure simplifies the transmission system, reduces equipment energy consumption and cost, and ensures that the upper and lower cleaning rollers work together at a stable speed, improving cleaning efficiency and consistency. It avoids uneven cleaning caused by speed differences and does not affect the adjustment of the second cleaning roller according to the different thicknesses of the PVC sheet.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: Please refer to Figure 1-8 This utility model provides the following technical solution: A production equipment for anti-aging, high-ductility PVC sheets, comprising a main body 1 and PVC sheets 102. A conveying roller 2 is provided on the inner wall of the main body 1, and a winding roller 3 is fixedly installed at the end of the main body 1. A cleaning mechanism for dust removal from the surface of the PVC sheets 102 is provided on the inner wall of the main body 1. The cleaning mechanism includes a first cleaning roller 4 and a second cleaning roller 5 rotatably installed on the inner wall of the main body 1. A first end face gear 401 is fixedly installed at the end of the first cleaning roller 4, and a second end face gear 501 is fixedly installed at the end of the second cleaning roller 5. A drive motor 6 is fixedly installed on the outer wall of the main body 1. A drive shaft 601 is fixedly installed at the output end of the machine 6, and a drive gear 602 is fixedly installed at the end of the drive shaft 601. The first cleaning roller 4 is located between the conveying roller 2 and the winding roller 3, and the first cleaning roller 4 and the winding roller 3 are on the same horizontal plane. The outer wall of the first winding roller 3 is in contact with the bottom outer wall of the PVC sheet 102. The second cleaning roller 5 is located on top of the first cleaning roller 4, and the second cleaning roller 5 is arranged parallel to the first cleaning roller 4. The outer wall of the second cleaning roller 5 is in contact with the top outer wall of the PVC sheet 102. The drive gear 602 is a long gear, and the drive gear 602 is meshed with both the first end face gear 401 and the second end face gear 501.

[0029] During the operation of this anti-aging, high-ductility PVC sheet production equipment, the PVC sheet is conveyed by the conveyor roller 2 to the winding roller 3 for winding. During this process, the cleaning mechanism performs dust removal. The drive motor 6 is started, driving the drive shaft 601 to rotate, which in turn causes the drive gear 602 at the end of the drive shaft 601 to rotate. Since the drive gear 602 is meshed with both the first end face gear 401 at the end of the first cleaning roller 4 and the second end face gear 501 at the end of the second cleaning roller 5, the drive gear 602 simultaneously drives the first end face gear 401 and the second end face gear 501 to rotate, thereby… This allows the first cleaning roller 4 and the second cleaning roller 5 to rotate synchronously in opposite directions. The first cleaning roller 4 is located between the conveying roller 2 and the take-up roller 3 and is on the same horizontal plane as the take-up roller 3. Its outer wall is in contact with the bottom outer wall of the PVC sheet. The second cleaning roller 5 is located on top of the first cleaning roller 4 and is set parallel to it. Its outer wall is in contact with the top outer wall of the PVC sheet. In this way, during the conveying of the PVC sheet, the first cleaning roller 4 and the second cleaning roller 5, which rotate synchronously in opposite directions, can simultaneously perform dust removal operations on the upper and lower surfaces of the sheet, thoroughly removing the dust attached to the surface of the sheet and avoiding dust residue from affecting the quality of the sheet and its subsequent use.

[0030] Example 2: Based on Example 1, a squeezing mechanism is also disclosed, the specific structure of which is as follows: The end of the second cleaning roller 5 is provided with a squeezing mechanism for squeezing the second cleaning roller 5. The squeezing mechanism includes an adjusting block 7 slidably installed inside the equipment body 1, and a slider 701 is fixedly installed on the outer wall of the adjusting block 7. A guide rod 8 is fixedly installed inside the equipment body 1, and a squeezing spring 801 is sleeved on the outer wall of the guide rod 8. The adjusting block 7 is annularly arranged, and the adjusting block 7 is rotatably connected to the end of the second cleaning roller 5, and the adjustment... Block 7 is symmetrically arranged at both ends of the second cleaning roller 5. Two sets of sliders 701 are symmetrically arranged on the outer wall of the adjusting block 7. The outer wall of the main body 1 of the equipment is provided with a groove 101 corresponding to the adjusting block 7 and the slider 701. Two sets of guide rods 8 are symmetrically arranged on the inner wall of the groove 101. The length of the guide rods 8 is the same as the length of the groove 101. The guide rods 8 are slidably connected to the slider 701. One end of the compression spring 801 is in contact with the top outer wall of the slider 701, and the other end of the compression spring 801 is in contact with the top inner wall of the groove 101.

[0031] The extrusion mechanism is mainly used to ensure the adhesion between the second cleaning roller 5 and the surface of the PVC sheet, so as to adapt to PVC sheets of different thicknesses. When PVC sheets of different thicknesses pass between the first cleaning roller 4 and the second cleaning roller 5, the PVC sheets will exert an upward or downward force on the second cleaning roller 5. This force will cause the adjusting block 7 to slide on the guide rod 8 through the slider 701, and the extrusion spring 801 will be compressed or extended accordingly. Through the elastic deformation of the spring, the adhesion pressure between the second cleaning roller 5 and the surface of the PVC sheet is automatically adjusted, which ensures that the cleaning roller and the sheet are in close contact for effective dust removal, while avoiding excessive pressure that could damage the surface of the sheet, thus improving the compatibility and adaptability of the equipment to sheets of different specifications.
